Chlorinated Rubber (CR) - High Hardness Thermoplastic Resin from China Suppliers & Factory for Superior Weather Resistance
PRODUCT INTRODUCTION
Chlorinated Rubber (CR) is a high hardness, powdered thermoplastic resin. And it is a derived product modified from the natural rubber through chlorination. It has excellent properties of weather resistance, adhesion, chemical stability, salt water resistance, UV protection, etc.
Chlorinated Rubber can be stably dissolved in toluene, xylene and other organic solvents, and acrylic acid, alkyd and many other resins, forming colorless or yellow transparent liquid. When this solution is applied to metal, concrete, paper and other surfaces, the solvent evaporates at room temperature, leaving behind a transparent, hard, shiny, glassy film. This film prevents the penetration of water vapor and oxygen, meanwhile is highly stable to various chemicals, such as acids and bases. It protects the substrate against corrosion and can be used as a topcoat for decoration. In addition, this product has excellent fire-resistance due to its high chlorine content.
In coatings to remarkably improve the coating properties such as weatherability and water resistance, insulation, inflammability, anti-acidity, anti-alkali, adhesion as well as impact strength. The chlorinated rubber coatings is widely applied to surface protection of materials for severe situation, such as shipping, offshore platforms, bridges, docks, containers, motor vehicle chassis, road signs, chemical equipment, etc. Additionally, high viscosity chlorinated rubber is applied to high-strength adhesives production, or added into other rubber products to improve its quality, while the low-viscosity product is applied to high-grade ink making.

Frequently Asked Questions (FAQ)
What are the primary characteristics of Chlorinated Rubber (CR)?
Chlorinated Rubber is a high-hardness, powdered thermoplastic resin modified from natural rubber. It features excellent weatherability, strong adhesion, chemical stability, salt water resistance, UV protection, and fire resistance.
Which solvents and resins are compatible with Chlorinated Rubber?
Chlorinated Rubber dissolves stably in organic solvents such as toluene and xylene, and blends well with acrylic acid, alkyd, and various other resins to form a transparent protective film.
What are the main applications of Chlorinated Rubber coatings?
They are widely applied for heavy-duty surface protection in harsh environments, including shipping, offshore platforms, bridges, docks, containers, motor vehicle chassis, road signs, and chemical equipment.
How does viscosity determine the use of different Chlorinated Rubber grades?
High-viscosity Chlorinated Rubber is typically used for producing high-strength adhesives or reinforcing rubber products, whereas low-viscosity grades are ideal for high-grade ink manufacturing.
What are the recommended packaging and storage conditions?
It is packaged in 20 kg plastic bags lined with PP woven bags. It should be stored at room temperature in a dry, well-ventilated location, and protected carefully against moisture.
